Hi All -
I'm seeing some strange behavior on a dev server. Right now the riak kv 2.2.0
server has 9GB free Ram, and no keys/values stored in Riak at all. (I've been
trying to figure out what's going on with the server, so I completely wiped
/var/lib/riak and re-installed from packagecould). Ulimit -n is set
appropriately as well.
If I make the following changes to /etc/riak/riak.conf I get crash error
messages:
storage_backend = leveldb
search = on
Turning search on with bitcask results in no such crash/error messages. When
switching between bitcask/leveldb on this test instance, i'm wiping the
/var/lib/riak directory each time.
Not much is turning up in google, and there is definitely plenty of memory
available for allocation.
Just wondering if anyone else has seen this.
Thanks!
The error messages:
